Once more, it seems the

ancestor of eukaryotes was more complex than previously thought! 😀 (reminds me of the unicellular ancestor of animals). In this occasion, it is the use of de novo protein structure modeling & sensitive sequence similarity algorithms that helped
Our latest: Using de novo protein structure prediction and sensitive sequence searches we found many new eukaryotic signature proteins in Asgard archaea, suggesting the archaeal ancestor of eukaryotes was more complex than previously assumed.

Three decisions will be crucial when starting your lab: 1) what to investigate (line of research), 2) where (institution/university/city/country), & 3) with who(the team). I would argue that 2 & 3 are the more important ones. A bad decision in those can really affect your career.

The

, a potential new organelle resulting from a
#symbiosis
between a nitrogen-fixing bacterium and an alga. The result is an adaptation of the microalgae Braarudosphaera bigelowii to nitrogen-limited waters. As
@RMassanaM
mentions in his nice comment
A nitrogen-fixing organelle, or “nitroplast,” has been identified in a marine alga. This discovery sheds light on the evolutionary transition from endosymbiont to organelle.

Amazing cover featuring a fascinating cell behavior of a ciliate! 🦠✨ Times are changing! These discoveries and these poorly-known organisms, once mostly confined to specialized journals, are now hitting the mainstream. Exciting times for

The tiny predator Lacrymaria olor owes its shape-shifting ability to an “origami-like” cellular architecture, a new Science study finds. The results offer a glimpse into geometrical control of behavior in single cells.
